Final answer:
The slope of a trend line passing through (1, 3) and (10, 25) is 22/9, which is not an option in the provided choices, indicating a possible error in the question.
Step-by-step explanation:
The slope of a trend line that passes through the points (1, 3) and (10, 25) can be calculated using the slope formula, which is (y2 - y1) / (x2 - x1). Plugging in our points, we have (25 - 3) / (10 - 1), which simplifies to 22 / 9. So, the slope of the line is 22 / 9, which is not one of the options provided (A. 0, B. -15, C. 15, D. 2). Hence, there must be an error in the given options. Normally, to find the slope between two points, you would subtract the y-coordinates and divide by the difference in the x-coordinates, just as illustrated in this example. Should the options have included a decimal or fraction, 22 / 9 or approximately 2.44 would have been the correct answer.
